Jeffrey Yao proves a sad truth in our countries current hot debate for it is not the equipment that does the killing but the one who possesses it. Although Jeffrey destroyed one life if it was the life of someone you loved you might want the equipment banned as well. It also doesn’t mean that someone who is more equipped or motivated with such devices couldn’t due more as we’ve seen in other incidents. So we come back to the same truth no matter what the equipment we need better defenses to prevent such horrendous attacks on individuals and surveillance of individuals who would use any equipment to maim another.
